# Varda-single-1.0

Live demo of [MeteoSwiss/Varda-single-1.0](https://huggingface.co/MeteoSwiss/Varda-single-1.0), a stretched-grid
(1 km regional / 31 km global) graph-transformer weather forecaster built with [Anemoi](https://anemoi.readthedocs.io/).

Initial conditions are pulled live from MeteoSwiss' KENDA-CH1 analysis (open data, data.geo.admin.ch) and
ECMWF's IFS open data (CC BY 4.0). Model weights: CC BY 4.0, © MeteoSwiss.
